Mario, @ 6:38 you state that the answer is x=-1 but in the top equation you have it at 5x-2y= +1. Was there a written typo before getting started or was the equation accidentally miscalculated? I ask because the previous two problems, which I have a lot of trouble understanding in class, we're explained beautifully, but when Ex. 3 came, at the end I was confused.
